Distances

A distance table of ports between Szczecin and other inland Polish and Western European ports, showing possible inland connections (see enclosed map and table).

The length of the Odra in kilometres begins from the mouth of the Opava river in the Czech Republic (0 km) and continues downstream. Kilometre marker boards with even values on the right-hand side of river and odd on the left-hand side, half kilometres not being marked.

The above-mentioned stretch of waterways includes:

542.4 km - the mouth of the Nysa Luzycka; the Odra river becomes the frontier river between Poland and Germany,

553.4 km - Eisenhьttenstadt; the Odra - Spree Canal,

Navigation of water levels

• The draught for vessels is dependent upon the present transit draughts which are given to the Inspectorates of Inland Shipping and any other interested persons by the administration of the waterway, the Regional Water Management Office, Szczecin (Regionalny Zarzad Gospodarki Wodnej, www.rzgw.szczecin.pl).
• The hydrological information referring to the present transit draughts are announced by the Institute of Meteorology and Maritime Industry (Instytut Meteorologii i Gospodarki Wodnej), broadcast on Polish radio - Channel 1 from Warsaw, 225 kHz, 1155 hrs.).
• A transit draught or a vessel draught is determined by the vessel size, the push-tow size or the composite unit size and the draught of the waterway. It should be:
  • for vessels which the draught is less than 140 cm:
  • proceeding up-stream ≥15 cm
  • proceeding down-stream ≥10 cm
  • for vessels which the draught is more than 140 cm:
  • proceeding up-stream ≥20 cm
  • proceeding down-stream ≥5 cm
  • for the vessels carrying dangerous goods the difference should be increased by a minimum of 20 cm, in addition to the above figures.
• Inland shipping in high waters is subject to the following restrictions:
  If the water levels attain or exceed high-water mark I (WWZ I) on the water gauges, the following shipping rules must be followed by the vessels:
  • equipped with efficient radiotelephones which ensure radiowatch for ship to ship communications (channel 10), and the reception of navigational information,
  • equipping with efficient radio receivers. In addition, the ship is forbidden to stop in the main waterways at night.
  If the water levels attain or exceed high-water mark II (WWZ II) on the one of the pair of water gauges (border stretch of river), or high - water mark II (WWZ II) on rest of internal inland waterways inland is forbidden. The vessel proceeding should call to the safe or proctected port before exceeding to the high-water mark or the high-water mark II.
  The high-water marks I and II (WWZ I and WWZ II) on the particulars water gauges are the following (border stretch of river) and high-water mark (remaining internal inland waterwayws):
